Any kind of software. Any language. For instance C#, C++, Java, Kotlin, Rust, Erlang, Ruby. I have worked with lots of different systems and platforms. Server applications, embedded systems and UI applications.

IT is a fast moving target. Do you use state of the art technology? Get up-to-date how software is developed today, using agile methods, test-driven development, modern tooling (IDEs, software configuration management, CI, deployment) and safe languages.

Review & Refactoring

Your software has performance, security or quality issues ("bugs")? I offer Code reviews and Security audits. In the long term, Refactoring can save time and money. Reviews involve coaching of developers, so that they improve their skills.
